Who Are Luniz? Hip-Hop Group Behind 'Us' Trailer Song 'I Got 5 on It'

Yukmouth and Numskull from Luniz perform onstage during the 93.5 KDAY Krush Groove 2017 concert at The Forum on April 22, 2017 in Inglewood, Calif.

Hip-hop fans from the mid-1990s who caught the new trailer for Jordan Peele's upcoming horror flick Us on Christmas Day (Dec. 25) probably felt a wave of nostalgia wash over when they heard the Luniz classic "I Got 5 On It" playing in the opening sequence.

The creepy teaser for the film -- Peele's follow-up to his Oscar-winning Get Out -- begins with an African-American family cruising down a desolate road with "I Got 5 On It" blasting through the car stereo. "That's a classic right there," the father tells his smiling wife, bumping his head along to the that samples Club Nouveau's 1987 jam "Why You Treat Me So Bad." The couple's confused young son in the back seat, meanwhile, asks his parents about the track's drug-referencing lyrics.

It's a scene that probably hits home with many thirty-something parents who grew up listening to "I Got 5 On It" during their teenage years. It's arguably the most notable weed song ever, and is based on a simple rule: everyone who pitches in gets to indulge. "I got five on it/ Grab your 40, let's get keyed/ I got five on it/ Mess' wit that indo weed," goes the song's chorus.

To those familiar with weed culture, the track's title is a reference to going halfsies on a $10 dime bag of marijuana with another person. It was the lead single from Luniz's 1995 debut album, Operation Stackola, and the duo's biggest hit to date.

In its heyday, "I Got 5 On It" hit No. 2 on Hot Rap Songs, No. 4 on Hot R&B/Hip-Hop Songs and No. 8 on the Billboard Hot 100 in 1995. And it's still heard regularly on classic hip-hop and R&B radio stations around the country. The song has drawn 141 million U.S. streams (on-demand audio and video and programmed streams combined) and sold 593,000 downloads to date, according to Nielsen Music.

Its parent album, Operation Stackola, spent two weeks at No. 1, where it debuted, on Top R&B/Hip-Hop Albums in 1995. The set has sold 1.1 million to date. Recorded in 1993 by Oakland, Calif., rappers Yukmouth and Numskull (aka Luniz), with additional vocals by singer Michael Marshall, the Tone Capone-produced track not only samples Club Nouveau's "Why You Treat Me So Bad" (1987), but also Kool and the Gang's "Jungle Boogie" (1973) and Audio Two's "Top Billin'" (1987), according to whosampled.com. The remix featured many popular Bay Area rappers at the time, including Spice 1 and E-40.

“Num came up with the idea to do ‘5 On It’ so let’s not leave him out,” Yukmouth told the Murder Master Music Show in 2017. “We toured the planet off of that! That’s a classic it still gets played 25 years later to this day! If you been watching the NFL or the NBA they play our shit all the time.” In the years since its release, "I Got 5 On It" has been sampled on more than half a dozen other tracks, from Meek Mill's "Heaven or Hell" to Puff Daddy's "Satisfy You," Yo Gotti's "I Know," Busta Rhymes' "Hello" and Big Sean's "Five Bucks (5 On It)."
